Abstract
The utility model discloses a sealing device for a rotary pipe type sintering furnace, which comprises a furnace pipe (13). A sealing body (8) sleeved on the furnace pipe (13) is equipped with a flange (7) conveniently arranged on a storage bin, one side of the sealing body (8) close to the storage bin is provided with internal sealing fillers and an internal compressing pressure ring (10), one side of the sealing body (8) close to air is provided with external sealing fillers and an external compressing pressure ring (1), a cooling water jacket (3) is arranged on an outer ring of the sealing body (8), a sealing chamber (4) is mounted between the inner sealing fillers and the outer sealing fillers on the sealing body (8), a plurality of rolling cylinders (5) are disposed inside the sealing chamber (4), which forms a rolling cylinder bearing, and the sealing body (8) is equipped with an air inlet pipe (6) communicated with the sealing chamber (4). The utility model provides a sealing device for a rotary pipe type sintering furnace which is resistant in heavy load and high temperature, sealing and reliable, low in noise, long in service life, and comparatively large in the diameter of rotary pipe type furnace input and output materials.
Description
Technical field
The utility model relates to a kind of, particularly relates to a kind of rotary pipe type sintering furnace sealing device.
Background technology
The rotary pipe type sintering furnace is in recent years in industrial extensive application such as metallurgy, but for the kiln of large-scale heavy duty high temperature, the sealing problem at its turnover material two ends is difficult to solve always.Because this kiln weight is very heavy, generally all more than 20 tons; Diameter is very big, and Φ is more than 400; Temperature is very high, and more than 800 ℃, above reason all is the major reason that causes body of heater to be difficult to seal.
The utility model content
The technical problem of the required solution of the utility model provide a kind of can anti-heavy burden, high temperature, and the rotary pipe type sintering furnace sealing device of the bigger rotary pipe type kiln input and output material of diameter.
In order to solve the problems of the technologies described above, the rotary pipe type sintering furnace sealing device that the utility model provides, comprise boiler tube, on described boiler tube, be socketed with seal, described seal is provided with the flange of being convenient to be installed on the feed bin, described seal by feed bin one side be provided with in airtight and watertight padding and in compress pressure ring, described seal is provided with external seal filler and external compression pressure ring thereof by atmosphere one side, on described seal outer ring, be provided with cooling jacket, inside and outside being on the described seal, be provided with annular seal space between the airtight and watertight padding, be provided with a plurality of rollers and form roller bearing in described annular seal space, described seal is provided with the air inlet pipe that is communicated with described annular seal space.
Airtight and watertight padding is a polytetrafluoroethylene packing in described, and described external seal filler is a soft graphite weaving filler.
Adopting the rotary pipe type sintering furnace sealing device of technique scheme, is static seal between the flange of feed bin and seal.There is cooling jacket the seal outer ring, can take away because the fricative heat of sealing strip and boiler tube, reduce serviceability temperature, there is the two-stage packing seal the inner left and right sides, the elasticity of filler can be regulated freely by the pressure ring that compresses of both sides, pressure-fired nitrogen (or other inert gas) sealing is arranged in the middle of the gland sealed, form an annular seal space, the air that the seepage of trace is come on the left of stoping and the work atmosphere on right side, be provided with roller in the annular seal space, be equivalent to a roller bearing, can alleviate the friction between seal and the boiler tube, reduce noise and wearing and tearing, it is also very convenient that this structure is changed maintenance simultaneously.
The utility model be a kind of can anti-heavy burden, high temperature, and the bigger rotary pipe type kiln input and output material of diameter and sealing is reliable, noise is low, the rotary pipe type sintering furnace sealing device of long service life.
Description of drawings
Fig. 1 is that structure of the present utility model is always schemed.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, on boiler tube 13, be socketed with seal 8, seal 8 is provided with the flange of being convenient to be installed on the feed bin 12 7, seal 8 by feed bin 12 1 sides be provided with polytetrafluoroethylene packing 9 and in compress pressure ring 10, seal 8 is provided with soft graphite weaving filler 2 and external compression pressure ring 1 thereof by atmosphere one side, on seal 8 outer rings, be provided with cooling jacket 3, be provided with annular seal space 4 being on the seal 8 between two airtight and watertight paddings, be provided with a plurality of rollers 5 and form roller bearing in annular seal space 4, seal 8 is provided with the air inlet pipe 6 that is communicated with annular seal space 4.
Referring to Fig. 1, be static seal between the feed bin 12 that need seal and the flange 7 of seal 8, feed bin 12 right-hand members have designed a demountable blind flange 11, make things convenient for the replacing and the maintenance of seal 8.There is cooling jacket 3 seal 8 outer rings, can take away because the fricative heat of sealing strip and boiler tube 13, reduce serviceability temperature, there is the two-stage packing seal the inner left and right sides, the elasticity of filler can be regulated freely by the pressure ring that compresses of both sides, pressure-fired nitrogen (or other inert gas) sealing is arranged in the middle of the gland sealed, form an annular seal space 4, the air that the seepage of trace is come on the left of stoping and the work atmosphere on right side, roller 4 is arranged on the inner ring, be equivalent to a roller bearing, can alleviate the friction between seal 8 and the boiler tube 13, reduce noise and wearing and tearing, it is also very convenient that this structure is changed maintenance simultaneously.
